New treatment option for Non Small Cell Lung Cancer
Official title A ctDNA-guided Phase II Trial of Osimertinib in Combination With Sacituzumab Tirumotecan in EGFR-mutated Advanced NSCLC Patients With Positive ctDNA After lead-in Osimertinib Monotherapy
ClinicalTrials.gov ID: NCT07375316
What this study is testing
What is Osimertinib + Sacituzumab Tirumotecan?
Osimertinib + Sacituzumab Tirumotecan is an investigational medicine, given as an once-daily infusion into a vein, being studied as a potential treatment for non small cell lung cancer.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- EGFR-mutated advanced NSCLC patients without ctDNA clearance after lead-in osimertinib monotherapy have inferior PFS compared with those with ctDNA clearance. Consequently, these patients might need an intensified therapeutic strategy, such as osimertinib combined with chemotherapy or ADC.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
